Potassium Hydrogen Carbonate Answers
What type of bond is Potassium Hydrogen Carbonate?
Q. KH(CO3) is it ionic, or covalent, or metallic or some combination of two of those?
Asked by suuppp123 - Fri Apr 4 11:33:01 2008 - Chemistry - 5 Answers - Comments
A. In KHCO3 there are two types of bonding going on. In the ion CO3-2 there is covalent bonding between the C and O atoms. In the salt K+(H+)CO3-2 there is ionic bonding between the ions.

What is Hydrogen Carbonate + dilute Potassium Hydroxide?
Q. The question is: Identify an amphiprotic ion formed when compressed carbon dioxide is dissolved in water; and construct an ionic equation for the reaction of this ion with dilute potassium hydroxide solution.
Asked by - Tue Jul 19 13:34:36 2011 - Chemistry - 3 Answers - Comments
A. An amphiprotic molecule (or ion) can either donate or accept a proton, thus acting either as an acid or a base. CO2 + H2O --> HCO3- + H+...HCO3- = amphoprotic because it can gain a proton and become carbonic acid, H2CO3, or lose a proton and become the carbonate ion, CO3 2-

Q. Please provide a balanced chemical equation and justification as to why this happens. Thanks!
Asked by Brian (B-Rye) - Wed Feb 3 18:51:13 2010 - Chemistry - 1 Answers - Comments
A. An acid-base reaction takes place with the liberation of carbon dioxide gas. The visible sign of reaction is bubbling. Initially, the following double displacement reaction occurs: HBr (aq) + KHCO3 (aq) ---> KBr (aq) + H2CO3 (aq) However, carbonic acid is unstable and rapidly decomposes to water and carbon dioxide: H2CO3 (aq) ---> H2O (l) + CO2 (g) === The overall balanced equation is: HBr (aq) + KHCO3 (aq) ---> KBr (aq) + H2O (l) + CO2 (g)

is potassium hydrogen carbonate an acid salt?
Q. please explain why...
Asked by pristine - Fri Dec 8 00:43:26 2006 - Chemistry - 2 Answers - Comments
A. Actually, it is an acid salt that is alkaline in reaction. The definition of an 'acid salt' has nothing to do with its p H in solution. It just involves incomplete neutralization of an acid. However because carbonic acid is a VERY weak acid, even the acid salt ends up being alkaline. The 'neutral' salt, potassium carbonate is even more strongly alkaline. The p Ka of carbonic acid (both 1 and 2) are very high, which means very weak. Potassium bisulfate on the other hand is acidic in reaction. It too is an acid salt but sulfuric acid is a strong acid.
